This discussion is useless.

Fresh tyres are worth a lot more than KERS, which was only good for 0.3 sec per lap in Shanghai. On multiple occassions Vettel was able stay in front of Hamilton, who used KERS and DRS, on the straigth by driving a defencive line. Yet he was overtaken in one of the fastest corners of the track solely because Hamilton had fresher tyres.

Webber did not have KERS either and he blasted by Button without any problem because he had grippier tyres.

If you don't believe me, read the analysis of James Allen: http://www.jamesallenonf1.com/2011/0...se-grand-prix/

And it wasn’t because of the DRS wing, the pass Hamilton pulled on Sebastian Vettel happened in Turn 7, one of the faster corners on the track, when Vettel least expected it and it came about because of differences of strategy.

Or the analysis of Matt Beer: http://www.autosport.com/news/report.php/id/90818

The McLaren driver's three-stop strategy proved a better bet than Vettel's two stops, allowing Hamilton to hunt down and pass the tyre-hampered Red Bull in the final laps.
